Upgrade to 32 GB

Your 18 GB ran short in 33% of readings. At your busiest you needed about 24 GB: 15.0 GB in use plus 8.8 GB spilled onto the disk.

SAMPLE DATAConfidence: LowMeasured over 2 days, 6 captures

Why this confidence

6 captures over 2 days
fewer than 30 captures or 5 days: provisional

The numbers behind it

33%
Struggled for memory
Memory pressure red (needs more RAM), limit 5%
67%
Memory under strain
Memory pressure yellow or red, limit 25%
8.8 GB
Spilled onto the disk at your busiest
Swap on disk at busy hours, limit 4.0 GB
50%
Graphics chip maxed out
Captures with GPU at 80% or more, limit 20%

The graphics chip was saturated in a large share of captures, so a higher chip class is part of the answer.

What your laptop did, day by day

How often memory ran short

fineyellowred

One bar per day. The more yellow or red, the more strain.

Memory pushed out to disk

Swap at busy hours. Above the dashed line a day counts towards an upgrade.

Memory in use against what you have

Memory in use at busy hours. A bar at the dashed line used all the installed memory.

Prices are Apple's store prices on 2026-10-20 (NL including VAT, US before tax) and change; check the store before buying.

Limited to a higher chip class than yours, because the chip was saturated.

The chip class you need starts at 36 GB, above the 32 GB your memory alone needs.

Models are ordered by memory size, then by Apple's starting price for the model. Apple sets the price of larger memory inside its configurator, so the real price of the memory step is higher than the starting price shown.
